Man hospitalized after rescued by Marin teens from the water at Stinson Beach

A 32-year-old man was still hospitalized but expected to recover Monday, two days after he was found floating face down and rescued from the water at Stinson Beach, authorities said.

Daniel Beckman was found unconscious and wearing a wetsuit near the shore shortly before 2:30 p.m. Saturday, the National Parks Service said in a statement.

First to spot him were Branson High School freshmen Oliver Hawkes and Ernie Bates.

"I was on a surfboard and my friend (Bates) was swimming pretty far off from shore," Hawkes said. "Ernie noticed a floating black thing in the water kind of coming toward us. We thought it was a dead seal or something like that but I saw the shoulders of a person."

Hawkes, 15, of San Anselmo said he had seen an unattended body board in the water a few minutes earlier, and he realized he had likely just found the owner. The two teens pulled Beckman toward the shore, and two bystanders waded into the surf to help them.

The group pulled Beckman onto the sand and yelled for help, catching the attention of two park rangers. One ranger performed CPR on Beckman, who had no pulse and was not breathing, while the second ranger retrieved an automated external defibrillator.

Beckman gasped and started breathing sporadically on his own, and the rangers did not need to shock him with the AED. He was airlifted to Doctors Medical Center in San Pablo, where he remained Sunday.

Nobody saw Beckman in the moments before he became unconscious, so it is not clear if he was knocked out by an injury in the surf or an unrelated medical problem.

Beckman remained at the medical center Monday, and he was alert and breathing on his own, an employee said.

Beckman's hometown is unknown, but he was preparing to move to San Francisco, a friend told authorities.
